摘要： According to one aspect and example, a holographic recording system includes a light source, an object for modulating an object beam from the light source, and a relay system adapted to magnify (positive or negative) the modulated beam (e.g., an image of the object) to an output image. The object may include an SLM operable to modulate the object beam with an information layer comprising a plurality of data pages. The output image is directed to the holographic storage medium, where a reference beam is also directed, to record the resulting interference pattern. Additionally, the relay system converges the output image to an output Fourier plane, which may be disposed within the holographic storage medium. A filter may be placed at an intermediate Fourier plane located prior to the output Fourier plane, and a phase mask may be placed at the position of the output image.

摘要： The unsuitability of the retina of the eye as a reflective projection screen for image observation causes objective optometry to be expensive and of limited accuracy. The subjective assessment of image quality is the only way to make full use of the resolution capability of the eye. A subjective optometer for home use is disclosed with ample accuracy and confidence for mail order of prescription glasses. It overcomes the disadvantages of subjective optometry and is able to measure the refractive errors to the resolution limit of the eye, which is of great importance for the present state and relief of ametropia. Electronic recording and connectivity can be provided as an option.

摘要： Disclosed are optical systems and methods of producing obliquity corrected light beams, for example, holographic recording and retrieval systems that utilize an obliquity corrected reference beam. One method includes directing a light beam reflected from a prism mirror to a reference plane with an angle of incidence to the reference plane, wherein the prism mirror varies the width of the light beam according to the angle of incidence to the reference plane. The optical system may include a holographic data storage system and the reference plane may be associated with a holographic storage medium.
